The danger zone will consist of two areas: An outer area (Area 1) for larger caliber weapons and a smaller area (Area 2) for smaller caliber weapons that is set within Area 1. The datum for the coordinates in this section is NAD-83. (1)Area 1. The waters bounded by the following seven points: Point A (13°38'59.443" N; 144°51'11.522" E) following the mean high water line to Point B (13°38'36.722" N; 144°52'50.256" E), following the mean high water line to Point C (13°38'33.936" N; 144°52'53.031" E), Point D (13°40'8.336" N; 144°53'44.876" E), Point E (13°40'56.842" N; 144°53'42.808" E), Point F (13°41'28.434" N; 144°52'37.582" E), and Point G (13°41'3.344" N; 144°51'53.652" E).(2)Area 2. A subset of waters within Area 1 bounded by the following six points: Point A (13°39'7.432" N; 144°52'8.210" E) following the mean high water line to Point B (13°38'36.722" N; 144°52'50.256" E), following the mean high water line to Point C (13°38'33.936" N; 144°52'53.031" E), Point D (13°39'54.724" N; 144°53'37.400" E), Point E (13°40'25.737" N; 144°52'43.157" E), and Point F (13°40'6.494" N; 144°52'7.349" E).(b)The regulation.(1) The enforcing agency will designate which area will be closed for use on dates designated for live fire. No persons, watercraft, or vessels shall enter or remain in the area during the times designated for live fire except those authorized by the enforcing agency. All live-fire training will cease if a person, watercraft, or vessel inadvertently enters the designated area and may resume once they have cleared the danger zone. The Installation Range Control Officer will be responsible for submitting all local Notices to Mariners for specific dates of firing, which will be disseminated through the U.S. Coast Guard and on the Marine Corps Base Camp Blaz website. The area will be open to normal maritime traffic when the range is not in use.(2) When the range is in use red flags will be displayed from conspicuous and easily seen locations on the east and west boundaries of the danger zone to signify that the range is in use. These flags will be removed when firing ceases for the day.(3) During the night firing, red lights will be displayed on the east and west sides of the danger zone to enable safety observers to detect vessels that may attempt to enter the danger zone. All range flags and red lights will be visible from 360 degrees. Due to the depth of the ocean the danger zone will not be marked with buoys.(c)Enforcement. The restrictions on public access through the danger zone shall be enforced by the Commander, Marine Corps Base, Camp Blaz, and such agencies as the Commander may designate in writing.86 FR 56213, Oct. 8, 2021
